Antirattler device for doors



1932- o. c. RITZ WOLLER- ANTIRATTLER DEVICE FOR DOORS Filed May 10, 1930 Patented Dec. 27, 1932 OLIVER C. BITZ WOLLEB, OF CHICAGO, ILLINOIS ANTIRATTLCER DEVICE FOR. DOORS Application filed May 10,

My invention relates to anti-rattler devices for doors and particularly to devices of this t pe arranged for use in connection with the oors of automobiles. It is one of the objects of my invention to provide a device of this type which may be quickly and easily applied to doors not originally equipped with such devices, the arrangement being such that anyone can readily make the installation without the necessity for an drilling or other cutting operations and by the use of only the simplest and most common tools.

To this end, it is one of the objects of my invention to provide a device of this type in the form of a pad which may be applied to the face of one of the hinge plates, preferably through the medium of one of the screws by which such hinge plate is secured in position. It is another object of my invention to provide an improved form of ad by which a pneumatic action is attaine and assured for providing the desired cushioning and sound deadening effect.

It is anotherobject of my invention to im prove devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawing and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawing,-- Fig. 1 is a face view of my improved device in position upon the face of a hinge plate;

Fig. 2 is an enlarged sectional view, being taken substantially at line 2-2 of Fig. 1; and

49 Fig.

k 3 is a horizontal sectional view through the parts shown in Fig. 1 but with the door turned to changed position.

Referring now to the several figures of the drawing, in which corresponding parts are indicated by the same reference characters,

10 indicates a door post or the door post portion of a wall such as that comprising one side of the body of an automobile, such post F having a door 11 mounted thereon through the medium of a hinge comprising plates 12 1930. Serial No. 451,441.

and 13 of any approved form pivotally connected together through the medium of a hinge pin 14. In the construction shown, the hinge plate 12 is connected in position upon the post 10 by means of wood screws 15, while the hinge plate 13 is connected upon the door 11 by the use of Wood screws 16.

As is best shown in Fig. 2 of the drawing, my improved anti-rattler device comprises a coremember 17 in the form of a ring formed of cellular rubber, the form of cellularity being such that the air is incapable of escaping therefrom. The ring 17 of cellular rubher is encased within a covering member 18 formed of ordinary compact rubber, such covering member being preferably molded directly about the ring 17 so as to completely enclose such ring. As isclearly shown in said Fig. 2, the covering member 18 is formed so as to comprise tabs 19 at opposite ends extending beyond the ring 17, each of the tabs 19 being provided with an opening 20 therethrough for the insertion of a screw or other means for securing the device in position upon the face of the hinge plate 12. In the construction illustrated, the upper tab 19 of the device is secured in position by means of one of the screws 15 by which the hinge plate 12 is normally held in position upon the post 10.

In the construction shown, an opening 21 is also provided through the center of the device through the hard rubber portion thereof projecting inwardly beyond the body of the ring 17, whereby the device as a whole ma be secured in osition by the use of suc opening 21 in lieu of one of the openings 20 if desired. By this arrangement comprisin the three openings 20 and 21, I am enable readily to attach the device in position upon an ordinary type of hinge arrangement.

ith my improved device in position upon the face of one of the hinge plates of a door as illustrated in Fig. 3 of the drawing, when the dooris closed, the cooperating hinge plate is brought into engagement with the outer face of the device so asto compress the device as a whole between the two lates of the hinge so as to obtain a very consi erable pressure by pneumatic action outwardly against the door away from the hinge plate 12. As a result of such pressure, the door 11 is kept from rattling. By reason of my improved construction in which the pneumatic action 5 depends upon air entrapped within a cellular core portion of the device, the action of the' device is rendered positive, and the strength and life of the device are very gr ggtly increased.

While I prefer to employ the form of construction as shown in my drawing and as above described, it will be understood'that I do not limit my invention to the form shown except so far as the claims may be so limited by the prior art, it being understood that changes might well be made in the form of the device Withoutdeparting from the spirit 0 my invention.

claim 1. A device of the class described comprising, in combination, a member of cellular ruber, a sheet of relatively compact rubber on the rear face of said member and projecting at least one point beyond the adjacent portions of the member serving as a base for attaching said device in operative position, and
